You’re 18. You have so much time. I was a complete shut in until I was 24. Like I only played video games because I didn’t want to face my stuttering. As I got older I became more accepting of myself and how I speak. Now I have a great career and lead meetings with directors and 15+ people at a time. I never thought I’d be doing something like that with my severe stutter, but you know what? Nobody cares, at all. You can do anything you set your mind to! Don’t be too hard on yourself.
